Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
Answer:
Egg white and amino acid solution.
Explanation:
Egg white and amino acid solution are the two foods that are used for building of body parts because they have proteins in them that is responsible for the building of muscles of in human body. There are two components of egg i.e. white and yellow part. White is the proteinic part whereas yellow parts having fats and other nutrients. Amino acid solution has amino acids which is considered as the building block from which protein is made.

A Rayleigh wave is a seismic surface wave causing the ground to shake in an elliptical motion(they move in a surafce rolling manner). A seismic wave means a earthquake wave, so Rayleigh wave is realted to the motion of earth and its crust. Rayleigh waves are formed when the particle vibrate with the combination of both transverse and longitudinal waves. This vibration gives rise to a wave which moves elliptically backwards that is Rayleigh Wave. Rayleigh waves are really fast they move with the spped 10 times faster than the speed of light. Rayleigh waves are generated by the interaction of P or compressional and S or shear waves(P ans S Waves are inside the Earths Crust) at the surface of the earth.

Love waves or Q waves or Quer Waves are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. A Love wave is a surface wave having a horizontal motion only. Love waves are formed when the earth particles move in a transverse wave manner creating a wave travelling perpendicular to the direction the wave.

C. Their environment makes them change slowly over time.
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually change over time.
E. None of the above because I’m smart
